Embodiment Construction

[0037] figure 1 A simplified schematic diagram of a pair of smart glasses 50 according to a first embodiment of the invention is shown. The smart glasses 50 include spectacle lenses 52 , spectacle frames 51 accommodating the spectacle lenses 52 therein, and temples 53 for holding the smart glasses 50 on a user's head. Accordingly, the smart glasses 50 are configured to be worn on the user's head.

[0038] The smart glasses 50 comprise gaze detection means 20 by means of which gaze direction of the user's eyes 10 can be determined. To this end, the gaze detection device 20 comprises a laser device 3 and a control device 4 arranged to operate the laser device 3 to perform a corresponding method for detecting the gaze direction of the eye 10 . For compact design, the control device 4 is arranged in the temple 53 of the smart glasses 50 .

[0039] The laser device 3 comprises a total of five surface emitters 3a, 3b, 3c, 3d, 3e as laser sources. Four of the five surface emitter...

Abstract

The invention relates to a method for operating a pair of smart glasses. A smart glasses(50) include an input unit and / or output unit(7) and a gaze detection arrangement(20), wherein the gaze detection arrangement(20) detects any eye movement of an eye(10). The method includes the steps of irradiating at least one wavelength-modulated laser beam(1) to the eye(10), detecting an optical path length(2) of the emitted laser beam(1) based on laser feedback interferometry of the emitted laser radiation with backscattered radiation from the eye, detecting a Doppler shift of the emitted and backscattered radiation based on the laser feedback interferometry, and detecting an eye velocity based on the Doppler shift, and wherein the input unit and / or output unit is operated based on the optical path length(2) and / or the eye velocity.

Description

technical field [0001] The invention relates to a method for operating smart glasses and smart glasses. Background technique [0002] It is known to use eye tracking or eye detection (also known as ophthalmology) to determine eye movement and estimate gaze direction. It is also known to use smart glasses to project images onto eg the user's retina. Gaze detection is used, for example, to adjust the controls of the projection unit of a pair of smart glasses when displaying context sensitive information. US 7,637,615 B2 discloses such smart glasses using retinal projection and prism mirror based eye tracking. Known systems for eye tracking are generally based on detecting information about the position of the eye using camera-based systems or electrical or electromagnetic sensors in the area of ​​the eye. In addition, scanning laser systems are known, for example, which use micromirrors to scan the laser spot on the eye. All of these systems are typically of high complexit...
